Take a step back to 1983. ThinkGeek has these great 3D pixel mice from Super Mario Brothers, with a choice of the legendary mushroom-eating Brooklyn plumber, or hi best friend the invincibility star.
Strictly for geek nostalgia, the pain inducing shapes and old-fashioned mouse ball mean these mice are near useless. At least they are USB rather than PS2, and the two-button design puts them ahead of anything Apple was doing at the time. $25.
